Apex vs Lambada Framework: What are the differences?

Developers describe Apex as "Serverless Architecture with AWS Lambda". Apex is a small tool for deploying and managing AWS Lambda functions. With shims for languages not yet supported by Lambda, you can use Golang out of the box. On the other hand, Lambada Framework is detailed as "Build and deploy serverless applications using JAVA". Lambada framework is a REST framework that implements JAX-RS API and lets you deploy your applications to AWS Lambda and API Gateway in a serverless fashion. With Lambada you can migrate the existing JAX-RS applications with a very little effort and build scalable applications without having to deal with servers.

Apex and Lambada Framework belong to "Serverless / Task Processing" category of the tech stack.

Some of the features offered by Apex are:

• Supports languages Lambda does not natively support via shim, such as Go
• Binary install (useful for continuous deployment in CI etc)
• Project level function and resource management

On the other hand, Lambada Framework provides the following key features:

• Support for the most common JAX-RS annotations.
• XML based configuration for Lambda function including VPC, custom execution role
• Support for multiple stages and regions.

Apex and Lambada Framework are both open source tools. It seems that Apex with 7.84K GitHub stars and 568 forks on GitHub has more adoption than Lambada Framework with 236 GitHub stars and 47 GitHub forks.
